My invention relates to and has for its purpose the provision of a chair of simple, substantial and inexpensive construction, par-' although not necessaril ticularly adapted, for beach and campuse, and structural y characterized in such manner as to be rendered adjustable with the utmost ease and dispatch to comfortably support a person in various seated and reclining positions and at widely difl'erent elevations from the ground, all while enabling the chair to be readily folded into a compact flat parcel for I will describe only one form of chair embodying'my invention. the accompanying drawings, Figure 1 is a view showing in plan one form of folding chair embodying my invention, adjusted to supporta person substantially at the ground level Figure 2 is a view showing in side elevation partly broken away, the chair in the same position of adjustment illustrated in Figure 1;

Figures 3, 4 and .5- are views similar to Figure 2 and illustrating various positions of ad ustment of the chair;

I Figure 6 is a view of the chair in side elevation, and illustrating the manner in which the several sections of'the chair are associated in a partially folded position of the chair; and

Figure 7 is a view in side elevation illustrating' the chair in completely folded position.

Referring specifically to the drawings,

' wherein similar reference characters indicate similar parts throughout the several figures,

my invention comprises several sections, in.

the present instance five in number, desigconstructed of wood or other suitable material.

The section '10 constitutes a main frame and comprisesva pair of longitudinal members 15, 15, connected in spaced parallel relation by series of transverse slats '16 and 17, the series of slats 16 being secured to one side edge of the members and extending along the latter from one end thereof, and the se ries ofslats 17 being secured to the opposite the latter fromthe opposite end thereof.

PATENT "omen side edge of the members and extending along In the position of the chair shownin Fig ures 2, 3 and 4, the series of slats 16 are adapted to forma seat S, whereas in the position of the chair shown in Figure of slats 17 are adapted to form a backrest B, so that it may be broadly stated that the main] frame or section 10 is provided with.

5", the series a seat po'rtionand a back rest portion dis-- posed in the present instance on reverse sides and at opposite ends of the'frame,

Intermediate its ends and adjacent the innermost one of the slats 16, the section 10 has a back rest B which in the positions of the chair shown in Figures2, 3 and 4 is adapted to co-act with-the seat S. The section 11" is composed'ofa pair of longitudinal members '18, 18, connected in parallelism by a series of slats 19 to form a rigid frame) which is pivoted on the section 10 by means of a rod 20 extending through the longitudinal members 15, l 5,'and 18, 18, of the sections 10 and 11, respectively.

The section 11 is thus rendered angularlg adjustable on the section 10 to occupy variou open positions in which it co-acts with the seat S to form the back rest for" the latter,

and to occupy a folded position wherein it is disposed parallelto the section 10 with the longitudinal members 18 positioned within the longitudinal members 15. I

v The section 11 carries the section 12-vvhich constitutes a propping element P also in the form of a frame having a pair of longitudinal members 21 2l connected in parallelism by an intermediate transverse member 22 and an end transverse member 23. The section" 12 is pivotally mounted on the section 11 intermediate the ends of the latter, by means of a rod 2 1' which extends through the members "05 mounted thereon the section llconstituting extended beyond the members 21-21, so as to project across the longitudinal members 15-15 of the section to provide lugs 25-25 which are adapted to engage with notches 26 formed at corresponding intervals along the longitudinal members -15 for co-action with the notches in enabling the section 12 j to function as the propping element in supporting the section 11 in various positions of angular adjustment relative to the seat S.

The section 13 constitutes a support on the section 10 for elevating the forward end of the latter and hence the seat S, and comprises legs 27-27 connected in parallelism by slats 28 to form a rigid frame pivotally mounted on the forward end of the section 10 by means of a rod 29 extending through the legs 27-27 and through the longitudinal members 15-15 on the section 10 intermediate the ends of the latter and adjacent the innermost one;of the-series of slats 17, by means of alined p1ns '32 extending through the members 15-15- and 30-30 of the sections 10 and 14, respectively. The'section 14 is thus rendered adjustable to occupy a folded position parallel to the section 10 and an open positionfor use as the seat S in the position of the chair shown in Figure 5, or for use as supporting legs similar to the section 13 when the chair most for use with the back rest B at the desired angle for co-action with the is adjusted to theposition shown in Figure 3. The members or legs 30-30 ofthe section 14 are constructed to provide hooks 33-33 at one extremity, for hooked engagement with the lugs 25-25 of the section 12, so as to coact with the lu s when engaged with the innermost ones 0 the notches 26, in supporting the section 14 in seat forming osition under the weight of an occupant w en the chair occupies the position of adjustment shown in Figure 5. r

With the sections of the chair adjusted to the position shown in Figures 1 and 2, the section 10 is'adapted to rest flatwise on the ground so that the seat S is disposed upperdisposed seat S in supportinga person in any one of several reclinlng positions dependent on the adjustment of the propping element P or section 12 relative to the notches 26-26. It

will be clear that in this position of the chair, the sections 13 and 14 are folded underneath the section 10 so as not to interfere with the resting of the latter flatwise upon the ground.

In the position of the chair shown in Figure 3, the section 13 has been moved to its open position to form a support or legs to elevate the forward end of the seat S, whereas in the position of the chair shown in Figure 4, both the sections 13 and 14 have been moved to open position to act as supports for elevating both the forward and rear ends of the seat S so that the latter is substantiallyhorizontal.

It will be clear that in any of the above described positions of the chair the back rest B can be readily adjusted to the inclined position most suitable for the comfort of the occupant of the seat S.

In the event that a chair of greater height than that provided by the aforementioned adjustments is desired, the section 10 is inverted from its former position and the section 13 folded, after which the hooks 33-33 of the section 14 constituting the seat S are engaged with the lugs 26-26 of the section 12 constituting the propping element P, as shown in Figure 5, so that the seat S will be supported for use in co-action with the back rest B in supporting a person in a comfortable'seated position.

When the chair is to be stored or .transported, the several sections 11, 12, 13 and 14 are folded with respect to the section 10 in the order shown in Figure 6; and when the sections are completely folded as shown in Figure 7, the chair will form a compact and flat parcel of rectangular outline so as to occupy a minimum space.
